Description

Technical Field

[0001] The present invention relates to the technical field of steel belt welding machines, and specifically to a steel belt welding device with an interface grinding function. Background Art

[0002] The steel belt welding machine mainly uses laser welding. The laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy radiated by the laser diffuses into the interior of the material through heat conduction to melt the material. It is a new type of welding method, mainly for thin-walled materials. During welding, two sections of steel belts are manually inserted into the two ends of the welding machine, and the reserved weld seam is welded by laser.

[0003] In the prior art, when using a laser welding machine to weld the interfaces of two sections of steel belts, the two sections of steel belts are mainly adjusted to be parallel and aligned by workers. This manual observation alignment may be skewed and offset. Without detection and calibration, the skew rate of steel belt welding remains high. By using an external device for detection and then adjusting by workers, the welding efficiency of the steel belt will decrease. Summary of the Invention

[0004] The purpose of the present invention is to provide a steel belt welding device with an interface grinding function to solve the problems in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A steel belt welding device with an interface grinding function includes a chassis, a welding table, a machine case, a feeding mechanism, an air detection mechanism, and a welding and grinding mechanism. The welding table, the machine case, the feeding mechanism, the air detection mechanism, and the welding and grinding mechanism are all fixedly connected to the chassis. There are two groups of feeding mechanisms and air detection mechanisms. The two groups of feeding mechanisms and air detection mechanisms are respectively arranged on both sides of the welding table. The feeding mechanism is fixedly connected to the air detection mechanism and the welding and grinding mechanism. The feeding mechanism and the air detection mechanism are both electrically connected to the machine case through electrical signals.

[0006] This welding device is used for welding and grinding two sections of precision stainless steel belts. The two sections of steel belts are respectively input by the feeding mechanisms located on both sides of the welding table. During the feeding process, the air detection mechanism detects the offset degree of the steel belts and sends an electrical signal to the machine case. The machine case controls the feeding mechanism to adjust the offset degree of the steel belts to ensure that the steel belts input from both sides are horizontally aligned. The joint of the two sides of the steel belts is located on the welding table. The welding and grinding mechanism first welds the weld seam and then grinds the weld seam.

[0007] Furthermore, the feeding mechanism includes a box shell, a feeding roller set, a pushing cylinder, a pressing table, a torsion mechanism, and a pushing-up mechanism. The box shell, the torsion mechanism, and the pushing-up mechanism are all fixedly connected to the chassis. The feeding roller set and the pushing cylinder are both fixedly connected to the box shell. The pressing table is fixedly connected to the output end of the pushing cylinder. The box shell is provided with a feeding groove, a first through hole, a second through hole, a first pipe hole, and a second pipe hole. The feeding groove is arranged on the side wall of the box shell. The first through hole is rotationally connected to the torsion mechanism. The second through hole is rotationally connected to the pushing-up mechanism. There are several groups of first pipe holes. The second pipe hole and several groups of first pipe holes are all fixedly connected to the air inspection mechanism. The torsion mechanism is electrically connected to the chassis. The torsion mechanism is slidably connected to the pushing-up mechanism. The box shell is fixedly connected to the welding and grinding mechanism.

[0008] The steel strip enters the gap between the upper and lower rollers of the feeding roller set along the feeding groove. The feeding roller set outputs torque to transport the steel strip. One side of the steel strip is located in the air inspection mechanism. The air inspection mechanism detects whether the steel strip generates an offset during transportation. When the steel strip generates an offset, the air inspection mechanism sends an electrical signal to the chassis. The torsion mechanism drives the steel strip to rotate according to the electrical signal of the chassis to correct the offset generated by the steel strip. After the adjustment is completed, one end of the steel strip is transported to the welding station. The pushing-up mechanism lifts the steel strip, and the pushing cylinder pushes the pressing table down to clamp and fix the steel strip. After the welding is completed, the steel strip is discharged along the feeding groove from the side away from the air inspection mechanism.

[0009] Furthermore, the torsion mechanism includes a first motor, a first gear, a bottom table, and a tooth column. The first motor is fixedly connected to the chassis. The output end of the first motor is rotationally connected to the first through hole. The output end of the first motor is fixedly connected to the first gear. The bottom table is provided with a ring gear pair, and the ring gear pair meshes with the tooth surface of the first gear. The bottom table is rotationally connected to the box shell. The tooth column is fixedly connected to the bottom table. The first motor is electrically connected to the chassis. The tooth column is slidably connected to the pushing-up mechanism.

[0010] The first motor outputs torque to the first gear according to the electrical signal of the chassis. Through the meshing of the first gear with the tooth surface of the ring gear pair arranged on the bottom table, the first gear transmits the torque to the bottom table, causing the bottom table to rotate around its axis. A tooth column is installed on the bottom table, and the pushing-up mechanism slides up and down along the tooth column.

[0011] Further, the upward pushing mechanism includes a second motor, a second gear, a sliding plate, a mounting ring, a hinged chassis, a top plate, a hydraulic rod, a suction cup, and a slide rail frame. The second motor is fixedly connected to the chassis. The output end of the second motor is rotatably connected to a second through hole, and the output end of the second through hole is fixedly connected to the second gear. An internal tooth groove is provided on the sliding plate, and the second gear meshes with the tooth surface of the internal tooth groove. The sliding plate is slidably connected to the slide rail frame, and the slide rail frame is fixedly connected to the box shell. The sliding plate is fixedly connected to the mounting ring, and the mounting ring is rotatably connected to the hinged chassis. The hinged chassis is slidably connected to the tooth column. The top plate is fixedly connected to the side of the tooth column away from the slide rail frame. A plurality of groups of sliding grooves are provided on the top plate, and the plurality of groups of sliding grooves are evenly distributed along the circumference of the top plate. The hydraulic rod is hinged to the hinged chassis, and the end of the hydraulic rod away from the hinged chassis is slidably connected to the sliding groove. The suction cup is rotatably connected to the end of the hydraulic rod away from the hinged chassis.

[0012] The second motor outputs torque to the second gear. By meshing the second gear with the tooth surface of the internal tooth groove provided on the sliding plate, the torque of the second gear is converted into the reciprocating up-and-down displacement of the sliding plate along the slide rail frame. The sliding plate drives the hinged chassis to slide up and down along the tooth column through the mounting ring. When the hinged chassis moves towards the top plate, while the hydraulic rod is compressed, the end away from the hinged chassis moves along the sliding groove towards the direction away from the center of the circle of the top plate, and the point where the suction cup contacts the steel belt is away from the geometric center of the steel belt, and the suction cup completes the adsorption of the steel belt.

[0013] Further, the air inspection mechanism includes an air pump, a sub-air pipe, inspection straight pipes, a collecting pipe, and an exhaust pipe. The air pump is fixedly connected to the chassis. The air pump and the sub-air pipe are connected through a pipeline. There are several groups of inspection straight pipes, and the several groups of inspection straight pipes are linearly and evenly distributed along the axis of the collecting pipe. The inspection straight pipes are connected to the sub-air pipe and the collecting pipe through pipelines respectively. The collecting pipe and the exhaust pipe are connected through a pipeline. The several groups of inspection straight pipes are fixedly connected to the first pipe hole, and the exhaust pipe is fixedly connected to the second pipe hole. The inspection straight pipes are connected to the chassis through electrical signals.

[0014] The air pump outputs air flow to the sub-air pipe, and the sub-air pipe evenly distributes the air flow into several groups of inspection straight pipes linearly and evenly distributed along the axis of the collecting pipe. One end of the steel belt is located in the several groups of inspection straight pipes linearly and evenly distributed. By statistically analyzing the deviation degree of one end of the steel belt in the several groups of inspection straight pipes, the overall deviation degree of the steel belt can be obtained. The gas in the inspection straight pipes is discharged through the collecting pipe and the exhaust pipe.

[0015] Further, the inspection straight pipe includes a right-angle elbow pipe, a partition plate, a semi-circular plate, and a flow meter. The right-angle elbow pipe is connected to the sub-air pipe and the collecting pipe through pipelines respectively. The partition plate, the semi-circular plate, and the flow meter are all fixedly connected to the right-angle elbow pipe. The partition plate is fixedly connected to the semi-circular plate. An arc groove is provided on the right-angle elbow pipe, and the arc groove is provided on the pipe wall of the right-angle elbow pipe. A plurality of groups of air holes are provided on the semi-circular plate, and the plurality of air holes are triangularly and evenly distributed on the semi-circular plate. The flow meter is connected to the chassis through an electrical signal.

[0016] One end of the steel strip is located in the arc groove at the bending position of the elbow pipe. When the steel strip is perpendicular to the partition plate, it completely blocks several groups of air holes on the semi-circular plate. The gas flow measured by the flowmeter is the gas flow on one side of the partition plate. When the steel strip is offset, some of the air holes on the semi-circular plate are not blocked, and the gas flow measured by the flowmeter changes. By receiving the electrical signals of several groups of flowmeters through the chassis and integrating the gas flow of each group of flowmeters, the overall offset situation of the steel strip can be obtained.

[0017] Furthermore, the welding and grinding mechanism includes a mounting frame, a third motor, a worm, a worm seat, a sliding table and a switching mechanism. The mounting frame is fixedly connected to the base frame and the third motor. The output end of the third motor is drivingly connected to the worm. The worm seat is provided with a threaded hole, and the worm is threadedly connected to the threaded hole. The worm seat is slidably connected to the sliding table, and the sliding table is fixedly connected to the casing. The switching mechanism is fixedly connected to the worm seat.

[0018] The third motor outputs torque to the worm. Through the threaded connection between the worm and the worm seat, the rotation of the worm is converted into the reciprocating sliding of the worm seat along the sliding table. The switching mechanism mounted on the worm seat slides along the weld to weld and grind the two steel strips.

[0019] Furthermore, the switching mechanism includes a bent column, a toothed disc, a fourth motor, a third gear, a grinding machine and a welding torch. The bent column is fixedly connected to the worm seat. The toothed disc is rotatably connected to the end of the bent column away from the worm seat. The fourth motor is fixedly connected to the bent column. The output end of the fourth motor is fixedly connected to the third gear. The third gear meshes with the tooth surface of the toothed disc. The grinding machine and the welding torch are both fixedly connected to the toothed disc.

[0020] After the welding torch slides along the weld to complete the welding of the two steel strips, the fourth motor outputs torque to the third gear. Through the meshing of the third gear with the tooth surface of the toothed disc, the toothed disc rotates around the axis of the end of the bent column away from the worm seat, and the grinding machine is rotated to the weld position through the rotation of the toothed disc.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention designs a gas detection mechanism. One end of the steel strip is located in the arc groove at the bending position of the elbow pipe. The steel strip completely blocks a number of air holes of the semi-circular plate when it is perpendicular to the partition plate. The gas flow measured by the flowmeter is the gas flow on one side of the partition plate. When the steel strip is offset, some air holes on the semi-circular plate are not blocked, and the gas flow measured by the flowmeter changes. By receiving the electrical signals of a number of flowmeters through the chassis and integrating the gas flow of each group of flowmeters, the overall offset situation of the steel strip can be obtained; The present invention designs a pushing-up mechanism. The second motor outputs torque to the second gear, and the second gear meshes with the internal tooth groove tooth surface provided on the sliding plate to convert the torque of the second gear into the reciprocating up-and-down displacement of the sliding plate along the slide rail frame. The sliding plate drives the articulated chassis to slide up and down along the tooth column through the mounting ring. When the articulated chassis moves towards the top plate, while the hydraulic rod is compressed, the end away from the articulated chassis moves along the chute towards the direction away from the center of the top plate, and the point where the suction cup contacts the steel strip is far from the geometric center of the steel strip, and the suction cup completes the adsorption of the steel strip; The present invention designs a torsion mechanism. The first motor outputs torque to the first gear according to the electrical signal of the chassis, and the first gear meshes with the tooth surface of the ring gear pair provided on the base table. The first gear transmits torque to the base table, causing the base table to rotate around its axis, adjusting the edge of the steel strip so that one end of it always fits the bending position of the elbow pipe, ensuring that the two steel strips are aligned and avoiding skew; The present invention can automatically load two steel strips, automatically detect whether the edges of the steel strips are aligned, align and calibrate the skewed steel strips, and polish the weld joints after welding, greatly improving the precision and efficiency of steel strip welding.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figure 1 shown, the technical solution of a steel belt welding device with an interface grinding function provided by the present invention includes a chassis 1, a welding table 2, a chassis 3, a loading mechanism 4, an air inspection mechanism 5, and a welding and grinding mechanism 6. The welding table 2, the chassis 3, the loading mechanism 4, the air inspection mechanism 5, and the welding and grinding mechanism 6 are all fixedly connected to the chassis 1. There are two sets of the loading mechanism 4 and the air inspection mechanism 5, and the two sets of the loading mechanism 4 and the air inspection mechanism 5 are respectively arranged on both sides of the welding table 2. The loading mechanism 4 is fixedly connected to the air inspection mechanism 5 and the welding and grinding mechanism 6, and the loading mechanism 4 and the air inspection mechanism 5 are both electrically connected to the chassis 3 through electrical signals.

[0034] This welding device is used for welding and grinding two sections of precision stainless steel strips. The two strips are respectively input by the feeding mechanisms 4 located on both sides of the welding table 2. During the feeding process, the air inspection mechanism 5 detects the deviation degree of the strips and sends an electrical signal to the chassis 3. The chassis 3 controls the feeding mechanism 4 to adjust the deviation degree of the strips to ensure that the strips input from both sides are horizontally aligned. The joint of the two strips is located on the welding table 2. The welding and grinding mechanism 6 first welds the weld seam and then grinds the weld seam.

[0035] As Figure 2 , Figure 3 , Figure 4 shown, the feeding mechanism 4 includes a box shell 41, a feeding roller group 42, a pushing cylinder 43, a pressing table 44, a torsion mechanism 45 and a pushing-up mechanism 46. The box shell 41, the torsion mechanism 45 and the pushing-up mechanism 46 are all fixedly connected to the chassis 1. The feeding roller group 42 and the pushing cylinder 43 are both fixedly connected to the box shell 41. The pressing table 44 is fixedly connected to the output end of the pushing cylinder 43. The box shell 41 is provided with a feeding groove 411, a first through hole 412, a second through hole 413, a first pipe hole 414 and a second pipe hole 415. The feeding groove 411 is arranged on the side wall of the box shell 41. The first through hole 412 is rotationally connected to the torsion mechanism 45. The second through hole 413 is rotationally connected to the pushing-up mechanism 46. There are several groups of the first pipe holes 414.

The torsion mechanism 45 is electrically connected to the chassis 3. The torsion mechanism 45 is slidably connected to the pushing-up mechanism 46. The box shell 41 is fixedly connected to the welding and grinding mechanism 6.

[0036] The strip enters the gap between the upper and lower rollers of the feeding roller group 42 along the feeding groove 411. The feeding roller group 42 outputs torque to transport the strip. One side of the strip is located in the air inspection mechanism 5. The air inspection mechanism 5 detects whether the strip generates deviation during transportation. When the strip generates deviation, the air inspection mechanism 5 sends an electrical signal to the chassis 3. The torsion mechanism 45 drives the strip to rotate according to the electrical signal of the chassis 3 to correct the deviation generated by the strip. After the adjustment is completed, one end of the strip is transported to the welding station. The pushing-up mechanism 46 lifts the strip, and the pushing cylinder 43 pushes the pressing table 44 to descend so that the strip is clamped and fixed. After the welding is completed, the strip is discharged from the side away from the air inspection mechanism 5 along the feeding groove 411.

[0037] As Figure 2 , Figure 3As shown, the torsion mechanism 45 includes a first motor 451, a first gear 452, a base 453, and a toothed column 454. The first motor 451 is fixedly connected to the base frame 1. The output end of the first motor 451 is rotatably connected to the first through hole 412. The output end of the first motor 451 is fixedly connected to the first gear 452. A ring gear pair 4531 is provided on the base 453. The ring gear pair 4531 is in meshing engagement with the tooth surface of the first gear 452. The base 453 is rotatably connected to the casing 41. The toothed column 454 is fixedly connected to the base 453. The first motor 451 is electrically connected to the chassis 3. The toothed column 454 is slidably connected to the upward pushing mechanism 46.

[0038] The first motor 451 outputs torque to the first gear 452 according to the electrical signal of the chassis 3. Through the meshing of the first gear 452 with the tooth surface of the ring gear pair 4531 provided on the base 453, the first gear 452 transmits the torque to the base 453, causing the base 453 to rotate about its axis. A toothed column 454 is installed on the base 453, and the upward pushing mechanism 46 reciprocates up and down along the toothed column 454.

[0039] As Figure 4 shown, the upward pushing mechanism 46 includes a second motor 461, a second gear 462, a slide plate 463, a mounting ring 464, a hinged chassis 465, a top plate 466, a hydraulic rod 467, a suction cup 468, and a slide rail frame 469. The second motor 461 is fixedly connected to the base frame 1. The output end of the second motor 461 is rotatably connected to the second through hole 413. The output end of the second through hole 413 is fixedly connected to the second gear 462. An internal tooth groove 4631 is provided on the slide plate 463. The second gear 462 is in meshing engagement with the internal tooth groove 4631. The slide plate 463 is slidably connected to the slide rail frame 469.

The suction cup 468 is rotatably connected to one end of the hydraulic rod 467 away from the hinged chassis 465.

[0040] The second motor 461 outputs torque to the second gear 462. The second gear 462 meshes with the tooth surface of the internal tooth groove 4631 provided on the slide plate 463, converting the torque of the second gear 462 into the reciprocating up-and-down displacement of the slide plate 463 along the slide rail frame 469. The slide plate 463 drives the articulated chassis 465 to slide up and down along the tooth column 454 through the mounting ring 464. When the articulated chassis 465 displaces towards the top plate 466, while the hydraulic rod 467 is compressed, the end away from the articulated chassis 465 displaces along the chute 4661 towards the direction away from the center of the circle of the top plate 466. The point where the suction cup 468 contacts the steel belt is away from the geometric center of the steel belt, and the suction cup 468 completes the adsorption of the steel belt.

[0041] As Figure 5 shown, the air inspection mechanism 5 includes an air pump 51, a sub-air pipe 52, a straight inspection pipe 53, a collecting air pipe 54, and an exhaust pipe 55. The air pump 51 is fixedly connected to the chassis 1. The air pump 51 and the sub-air pipe 52 are connected through a pipeline. There are several groups of straight inspection pipes 53, and several groups of straight inspection pipes 53 are linearly and evenly distributed along the axis of the collecting air pipe 54. The straight inspection pipes 53 are connected to the sub-air pipe 52 and the collecting air pipe 54 through pipelines. The collecting air pipe 54 and the exhaust pipe 55 are connected through a pipeline. Several groups of straight inspection pipes 53 are fixedly connected to the first pipe hole 414, and the exhaust pipe 55 is fixedly connected to the second pipe hole 415. The straight inspection pipes 53 are connected to the chassis 3 through electrical signals.

[0042] The air pump 51 outputs air flow to the sub-air pipe 52. The sub-air pipe 52 evenly distributes the air flow into several groups of straight inspection pipes 53 that are linearly and evenly distributed along the axis of the collecting air pipe 54. One end of the steel belt is located in several groups of straight inspection pipes 53 that are linearly distributed. By statistically analyzing the deviation degree of one end of the steel belt in several groups of straight inspection pipes 53, the overall deviation degree of the steel belt can be obtained. The gas in the straight inspection pipes 53 is discharged through the collecting air pipe 54 and the exhaust pipe 55.

[0043] As Figure 6 、 Figure 7 shown, the straight inspection pipe 53 includes a right-angle elbow 531, a partition plate 532, a semi-circular plate 533, and a flow meter 534. The right-angle elbow 531 is connected to the sub-air pipe 52 and the collecting air pipe 54 through pipelines. The partition plate 532, the semi-circular plate 533, and the flow meter 534 are all fixedly connected to the right-angle elbow 531.

The semi-circular plate 533 is provided with several groups of air holes 5331, and several air holes 5331 are triangularly and evenly distributed on the semi-circular plate 533. The flow meter 534 is connected to the chassis 3 through electrical signals.

[0044] One end of the steel strip is located in the arc groove 5311 at the bending position of the elbow 531. When the steel strip is perpendicular to the partition plate 532, it completely blocks a number of air holes 5331 on the semi-circular plate 533. The gas flow measured by the flowmeter 534 is the gas flow on one side of the partition plate 532. When the steel strip is offset, some of the air holes 5331 on the semi-circular plate 533 are not blocked, and the gas flow measured by the flowmeter 534 changes. By receiving the electrical signals of a number of flowmeters 534 through the chassis 3, the overall offset of the steel strip can be obtained.

[0045] As Figure 8 shown, the welding and grinding mechanism 6 includes a mounting frame 61, a third motor 62, a worm 63, a worm seat 64, a sliding table 65 and a switching mechanism 66.

The worm seat 64 is provided with a threaded hole 641, and the worm 63 is threadedly connected to the threaded hole 641. The worm seat 64 is slidably connected to the sliding table 65, and the sliding table 65 is fixedly connected to the housing 41. The switching mechanism 66 is fixedly connected to the worm seat 64.

[0046] The third motor 62 outputs torque to the worm 63. Through the threaded connection between the worm 63 and the worm seat 64, the rotation of the worm 63 is converted into the reciprocating sliding of the worm seat 64 along the sliding table 65. The switching mechanism 66 mounted on the worm seat 64 slides along the weld to weld and grind the two steel strips.

[0047] As Figure 9 shown, the switching mechanism 66 includes a bent column 661, a gear disk 662, a fourth motor 663, a third gear 664, a grinding machine 665 and a welding torch 666.

The third gear 664 is in meshing engagement with the tooth surface of the gear disk 662. The grinding machine 665 and the welding torch 666 are both fixedly connected to the gear disk 662.

[0048] After the welding torch 666 slides along the weld to complete the welding of the two steel strips, the fourth motor 663 outputs torque to the third gear 664. Through the meshing engagement between the third gear 664 and the tooth surface of the gear disk 662, the gear disk 662 rotates around the axis of one end of the bent column 661 away from the worm seat 64, and the grinding machine 665 is rotated to the weld working position through the rotation of the gear disk 662.

[0049] Working principle of the present invention: This welding device is used for welding and grinding two sections of precision stainless steel strips. The two strips enter the gap between the upper and lower rollers of the feeding roller group 42 through the feeding grooves 411 located on both sides of the welding table 2. The feeding roller group 42 outputs torque to transport the strips. During the feeding process, the air pump 51 outputs air flow to the sub-air pipe 52. One end of the strip is located in the arc groove 5311 at the bending part of the curved elbow pipe 531. When the strip is perpendicular to the partition plate 532, it completely blocks a number of air holes 5331 on the semi-circular plate 533. The gas flow measured by the flowmeter 534 is the gas flow on one side of the partition plate 532. When the strip is offset, some of the air holes 5331 on the semi-circular plate 533 are not blocked, and the gas flow measured by the flowmeter 534 changes. By receiving the electrical signals of a number of flowmeters 534 through the chassis 3, the overall offset of the strip can be obtained. The first motor 451 outputs torque to the first gear 452 according to the electrical signal of the chassis 3, causing the bottom table 453 to rotate around its axis. The second motor 461 outputs torque to the second gear 462. Through the meshing of the second gear 462 with the tooth surface of the internal tooth groove 4631, the sliding plate 463 drives the articulated chassis 465 to slide up and down along the tooth column 454 through the mounting ring 464. When the articulated chassis 465 moves towards the top plate 466, while the hydraulic rod 467 is compressed, the end far from the articulated chassis 465 moves away from the center of the top plate 466 along the sliding groove 4661. The point where the suction cup 468 contacts the strip is far from the geometric center of the strip, and the suction cup 468 completes the adsorption of the strip, ensuring that the strips input from both sides are horizontally aligned. The joint of the two strips is located on the welding table 2. The welding torch 666 slides back and forth along the sliding table 65 to weld the weld first, and then the grinding machine 665 grinds the weld.
